By mars 20, 2025mars 24th, 2025No Comments2 min read

To ensure your Performance Max (PMax) campaigns achieve optimal performance and deliver the best possible results, it’s crucial to implement a strategic approach. By following a set of best practices, you can maximize efficiency, improve targeting, and enhance overall campaign performance. Below are the essential steps you should take to set up, monitor, and optimize your PMax campaigns effectively.

1. Exclude Brand Terms

To prevent your PMax campaign from cannibalizing branded traffic, exclude your brand terms and capture them in a dedicated search or shopping campaign unless you have a strategic reason not to.

How to Exclude Brand Terms:

  • Navigate to your PMax campaign settings.
  • Click on the Settings button.
  • Scroll down to Additional Settings.
  • Locate the Brand Exclusions option and input your brand terms accordingly.

2. Implement the Latest Micro PMax Script

The latest Micro PMax script is a crucial tool for enhancing your PMax campaign’s performance.

Where to Find the Script:

  • The script is typically released on LinkedIn by the creator.
  • For members, it is also available at mikerhodes.circle.so under the Members section in the PMax Scripts category.

How to Add the Script:

  • Copy the code from the provided source.
  • Go to Tools in your Google Ads account.
  • Select Bulk Actions and then Scripts.
  • Paste the copied code into the script editor and ensure you update the necessary URLs or settings as specified in the instructions.

3. Use the PMax Placement Exclusion Script

This script helps identify low-quality placements in your PMax campaigns by creating a suggested exclusion list based on predefined parameters.

How to Access the Script:

  • The script is available on the creator’s website.
  • After implementing the script, review the generated list and exclude any unwanted placements from your PMax campaign.

4. Add Audience Signals

Audience signals are essential for guiding the algorithm in the right direction. However, it’s important to note that audience signals are not strict instructions — they simply provide helpful guidance to improve performance.

5. Manage Search Term Overlap

Be mindful of potential search term overlap, which can cause your PMax campaign to compete with your search campaigns. Here’s how Google prioritizes:

  • Exact Match Keywords will always take priority.
  • Phrase Match and Broad Match will compete with PMax campaigns based on Ad Rank.

Final Tip

For ongoing insights and practical strategies to optimize your campaigns, be sure to stay updated with trusted industry experts and resources. Implementing these best practices will help you maximize the success of your PMax campaigns.
